Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals with low cervical or thoracic spinal cord injuries or other paralyzing conditions who meet specific inclusion criteria.
✕Probably not a fit
Patients with certain medical conditions such as pacemakers, uncontrolled seizure disorders, or significant psychological issues may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates a surgically implanted functional electrical stimulation (FES) system designed to enhance exercise, standing, stepping, and balance in individuals with varying degrees of paralysis. Participants will undergo surgery to implant electrodes into the muscles of the trunk and legs, which are connected to a stimulator. Following implantation, patients will receive training in mobility skills using the FES system, along with a prescribed rehabilitation program. The study includes assessments of strength, balance, and functional abilities at multiple follow-up points after discharge.
Why it matters
Potential benefit: If successful, this approach could significantly improve mobility and quality of life for patients with paralysis.
How similar studies have gone: Other studies have shown promise with similar functional electrical stimulation approaches, indicating potential for success.

Phase I Inclusion Criteria 1. Skeletal maturity and ability to sign informed consent (\>18 years) 2. Non-ventilator dependent paralysis resulting from injuries such as: mid cervical/thoracic (C4 or below) spinal cord injuries, poststroke hemiparesis, TBI, or MS, affecting the trunk and/or lower limbs 3. Innervated and excitable lower extremity and trunk musculature 4. Adequate social support and stability 5. Willingness to comply with follow-up procedures Phase I Exclusion Criteria 1. Non-English speaking 2. Females who are pregnant 3. Current pressure injuries that would be exacerbated by study activities 4. Severe contractures or uncontrolled spasticity of any major joint of the upper or lower extremities that results in a fixed deformity that would interfere with study activities 5. History of spontaneous fractures or other evidence of excessively low bone density 6. History of vestibular dysfunction, balance problems, or spontaneous falls 7. Acute and or/untreated orthopedic problems that would prevent a participant from weight bearing or exercising such as a dislocation or fracture.
